Abstract

Described is a rack designed to hold a stretcher in a vehicle such as an ambulance. The stretcher rack comprises a spring-mounted, raisable and lowerable, stretcher-bearing surface linked, by means of a parallelogram support arm and a base element, with the floor and which can be pulled out or pushed in while maintaining this link. This design makes it easier for medical attendants to handle the stretcher, since stretcher plus patient can be laid on the rack outside the ambulance. In addition, the invention has the advantage that the base element is the only element in contact with the floor, so that less of the vertical accelerations which occur during transport are transmitted to the stretcher on the stretcher-bearing surface.

Description

Die Erfindung betrifft ein Krankentragengestell zur Aufnahme einer Krankentrage in einem Verkehrsmittel nach dem Oberbegriff des Anspruchs 1.The invention relates to a stretcher frame for holding a stretcher in a means of transport according to the preamble of claim 1.

Ein Krankentragengestell in einem Verkehrsmittel des Rettungswesens, z.B. einem Krankenwagen oder einem Rettungsflugzeug, dient dazu, eine Krankentrage mit einem darauf liegenden Patienten während des Transports aufzunehmen.A stretcher rack in a rescue vehicle, e.g. an ambulance or an ambulance, is used to hold a stretcher with a patient lying on it during transport.

In dem "Handbuch des Rettungswesens", V. D. Linnepe Verlagsgesellschaft, W-5800 Hagen, ISBN 3-921297-13-3, Abschnitt G 1.1, Abs. 5.3 "Krankentragengestell" sind wesentliche Eigenschaften beschrieben, die ein Krankentragengestell zur Erfüllung seiner Transportaufgabe besitzen muß. Neben der Erleichterung des Be- und Entladens einer Krankentrage durch Absenken eines Aufnahmetisches und Anheben des Aufnahmetisches zur leichteren Behandlung des Patienten durch das Begleitpersonal soll der Patient auch weitgehend gegen die Schwingungen des Verkehrsmittels beim Transport isoliert werden.The "Handbuch des Rettungswesen", VD Linnepe Verlagsgesellschaft, W-5800 Hagen, ISBN 3-921297-13-3, Section G 1.1, Section 5.3 "Stretcher Rack" describes the essential properties that a stretcher rack fulfills must have its transport task. In addition to facilitating the loading and unloading of a stretcher by lowering a receiving table and lifting the receiving table to make it easier for the attending staff to treat the patient, the patient should also be largely isolated from the vibrations of the means of transport during transport.

Bisher ist es üblich, den Patienten zunächst auf eine Krankentrage außerhalb des Verkehrsmittels zu legen und dann die Krankentrage mit dem Patienten in das Verkehrsmittel zu schieben. Dabei wird die Krankentrage mit einer Stirnseite zunächst auf das Krankentragengestell aufgesetzt und dann in Längsrichtung verschoben, bis sie vollständig auf dem Krankentragengestell ruht.So far, it has been customary to first place the patient on a stretcher outside the means of transport and then to push the stretcher with the patient into the means of transport. The stretcher is first placed on the stretcher frame with one end face and then moved in the longitudinal direction until it rests completely on the stretcher frame.

Das Be- und Entladen von Krankentragen mit schweren Patienten erfordert vom Begleitpersonal erhebliche Kraftanstrengungen, wodurch eine koordinierte Hubbewegung häufig nicht mehr möglich ist und der Patient auf der Krankentrage in eine für ihn unangenehme Schräglage gebracht werden kann. Diese Gefahr wird besonders dadurch begünstigt, daß das Begleitpersonal während des Be- und Entladens an den Längsseiten der Krankentrage angreifen muß, wo sich bereits kleine ungleichmäßige Hebe- oder Senkbewegungen als starke Nickbewegungen der Krankentrage auswirken.Loading and unloading stretchers with heavy patients requires considerable effort by the attendant, which means that a coordinated lifting movement is often no longer possible and the patient can be brought into an inclined position on the stretcher. This danger is particularly favored by the fact that the accompanying personnel must attack on the long sides of the stretcher during loading and unloading, where small uneven lifting or Lowering movements act as strong pitching movements of the stretcher.

Aus der DE-U- 7 616 607, die dem Oberbegriff des Patentanspruchs 1 zugrundeliegt, ist ein Krankentragenlagerungsgestell in Krankenwagen bekannt, wobei das Gestell auf einem zur Befestigung am Krankenwagen bestimmten Unterteil und einem gegenüber dem Unterteil in Längs- und Querrichtung verschiebbar gelagerten Oberteil besteht. Das Oberteil ist mit dem Unterteil über parallele, im wesentlichen gleich lange Hebel verbunden. Diese Hebel können über einen Hydraulikantrieb parallel auf und ab verschwenkt werden. Zusätzlich ist noch ein weiterer Hebel vorgesehen, der an einer Tragplatte angreift und beim Verschwenken des parallelen Hebels eine zwangsweise Neigung des Oberteils des Krankentragenlagerungsgestells bewirkt.From DE-U- 7 616 607, on which the preamble of claim 1 is based, a stretcher support frame in ambulances is known, the frame consisting of a lower part intended for attachment to the ambulance and an upper part slidably mounted in the longitudinal and transverse directions relative to the lower part . The upper part is connected to the lower part via parallel levers of essentially the same length. These levers can be pivoted up and down in parallel via a hydraulic drive. In addition, a further lever is provided, which engages a support plate and, when the parallel lever is pivoted, causes the upper part of the stretcher support frame to be inclined.

Das Oberteil umfaßt eine Krankentragenaufnahme, die mittels an ihrer Unterseite angebrachter Stangen und Führungen in Längsrichtung verschoben und zum Teil aus dem Wagen herausgezogen werden kann.The upper part comprises a stretcher holder, which can be moved in the longitudinal direction by means of rods and guides attached to its underside and can be partially pulled out of the carriage.

Außerdem ist aus der FR-A1 25 06 154 eine Vorrichtung zum kombinierten Anheben und Überführen von Behinderten-Rollstühlen in ein Fahrzeug bekannt. Die Vorrichtung umfaßt eine seitlich aus dem Fahrzeug heraus und auf den Boden absenkbare Plattform, auf die ein Rollstuhl etwa ebenerdig heraufgefahren werden kann. Aufnahmemulden für die Räder des Rollstuhls sorgen für eine Stabilisierung bei Bewegungen der Plattform. Die Plattform ist über zwei seitlich angreifende Parallelogrammträgerarme mit einem auf dem Fahrzeugboden verschiebbar angeordneten Basisteil verbunden. Die unteren Trägerarme sind an ihren der Plattform abgewandten Enden gekröpft und gleiten auf fest im Fahrzeug angeordneten Rollen. Nach Art eines Kulissenantriebs wird so bei reiner Horizontalverschiebung des Basisteils eine kombinierte Horizontal- und Vertikalbewegung der Plattform erreicht.In addition, from FR-A1 25 06 154 a device for the combined lifting and transferring of handicapped wheelchairs into a vehicle is known. The device comprises a platform that can be lowered out of the side of the vehicle and onto the floor, onto which a wheelchair can be raised approximately at ground level. Troughs for the wheels of the wheelchair ensure stabilization when the platform moves. The platform is connected to a base part which is arranged to be displaceable on the vehicle floor via two laterally acting parallelogram support arms. The lower support arms are cranked at their ends facing away from the platform and slide on rollers which are firmly arranged in the vehicle. In the manner of a link drive, a combined horizontal and vertical movement of the platform is achieved with a pure horizontal displacement of the base part.

Ferner ist aus der DE-AS 21 29 320 eine Vorrichtung zur Aufnahme von Krankentragen in Krankenwagen bekannt, bei der eine Federung eines Tragrahmens dadurch erzielt wird, daß der Tragrahmen gegenüber dem Wagenkasten über zwei mit Federn verbundene Hebel elastisch abgestützt und gegen Verschieben in Längsrichtung gesichert ist. Die beiden Hebel stützen unabhängig voneinander den Tragrahmen von unten ab und die Sicherung gegen Längsverschiebung greift etwa in Höhe des Schwerpunktes des vollbeladenen Tragrahmens an.Furthermore, from DE-AS 21 29 320 a device for receiving stretchers in ambulances is known, in which a suspension of a support frame is achieved by that the support frame is elastically supported relative to the car body via two levers connected with springs and secured against displacement in the longitudinal direction. The two levers independently support the support frame from below and the securing against longitudinal displacement engages at about the center of gravity of the fully loaded support frame.

Außerdem ist in der US-PS 12 0̸0̸ 583 eine Vorrichtung beschrieben, mittels der eine Krankentrage horizontal vorwärts und rückwärts in ein Krankentransportfahrzeug hineingeschoben bzw. aus diesem herausgezogen werden kann. Dabei umfaßt die bekannte Vorrichtung einem Zapfen, auf dem das eine Ende der Trage aufgesetzt werden kann, so daß der an diesem Ende angreifende Krankenträger die Griffe der Krankentrage loslassen kann. Die Trage läßt sich anschließend in eine Position längs zur Fahrzeugachse verschwenken, in welcher sie dann in Längsrichtung verschoben werden kann.In addition, a device is described in US-PS 12 030̸ 583, by means of which a stretcher can be pushed horizontally forwards and backwards into a patient transport vehicle or pulled out of it. The known device comprises a pin on which one end of the stretcher can be placed, so that the patient at this end can release the handles of the stretcher. The stretcher can then be pivoted into a position along the vehicle axis, in which it can then be moved in the longitudinal direction.

Diese bekannten Vorrichtungen erfüllen nur teilweise oder gar nicht die im oben genannten "Handbuch des Rettungswesens" beschriebenen Eigenschaften, die ein Krankentragengestell zur Erfüllung seiner Transportaufgabe besitzen muß.These known devices only partially or not at all meet the properties described in the "Rescue Manual" mentioned above, which a stretcher frame must have in order to fulfill its transport task.

Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Krankentragengestell zur Aufnahme einer Krankentrage in einem Verkehrsmittel dahingehend zu verbessern, daß das Aufsetzen auf und Abnehmen der Kranktrage vom Krankentragengestell wesentlich erleichtert und der Transportkomfort verbessert wird.The invention is therefore based on the object of improving a stretcher frame for accommodating a stretcher in a means of transport such that putting on and taking off the stretcher from the stretcher frame is made considerably easier and the transportation comfort is improved.

Diese Aufgabe wird bei einem Krankentragengestell nach dem Oberbegriff des Anspruchs 1 durch die im kennzeichnenden Teil angegebenen Merkmal gelöst.This object is achieved in a stretcher frame according to the preamble of claim 1 by the feature specified in the characterizing part.

Das Krankentragengestell nach der Erfindung besitzt einen Aufnahmetisch, der aus dem Verkehrsmittel herausziehbar ist. Damit sind die Voraussetzungen geschaffen, daß der Aufnahmetisch auch unter das Höhenniveau des Bodens des Vekehrsmittels abgesenkt werden kann. Außerdem kann das Begleitpersonal an den Stirnseiten der Krankentrage angreifen, wo sich Unterschiede in den Hebe- und Senkbe wegungen weniger stark als Nickbewegungen auf die Krankentrage auswirken und der Patient somit beim Be- und Entladen wesentlich ruhiger liegen bleibt.The stretcher frame according to the invention has a receiving table which can be pulled out of the means of transport. This creates the prerequisites that the receiving table can also be lowered below the level of the floor of the transport means. In addition, the escort staff can attack on the front of the stretcher, where differences in lifting and lowering movements have less of an effect than pitching movements on the stretcher, so that the patient remains much calmer when loading and unloading.

Ferner kann die Krankentrage außerhalb des Verkehrsmittels vollständig auf den Aufnahmetisch gelegt werden. Es ist somit nicht mehr erforderlich, beim Hineinschieben der Krankentrage diese noch an einem Ende anheben zu müssen.Furthermore, the stretcher can be placed completely on the table outside the means of transport. It it is no longer necessary to have to lift the stretcher at one end when pushing it in.

Der Parallelogramm-Trägerarm sorgt dafür, daß bei Hebe- und Senkbewegungen die horizontale Ausrichtung der Krankentrage unverändert bleibt. Auch beim Hineinschieben der Krankentrage mittels des Krankentragengestells werden so unangenehme Nickbewegungen vermieden.The parallelogram support arm ensures that the horizontal orientation of the stretcher remains unchanged during lifting and lowering movements. Unpleasant pitching movements are also avoided when the stretcher is pushed in by means of the stretcher frame.

Durch die Lagerung des Parallelogramm-Trägerarm in einem Basisteil, welches die einzige Auflagefläche auf dem Boden des Verkehrsmittels bildet, ergibt sich eine wesentliche Verbesserung der Schwingungslsolierung. Einige bisher verwendete Krankentragengestelle ruhen nämlich an zwei oder auch vier Punkten auf dem Boden des Verkehrsmittels, so daß über alle diese Punkte Schwingungen eingeleitet werden können. Hieraus können sich auch Interferenzschwingungen ergeben, wenn unterschiedliche Belastungen an den einzelnen Auflagepunkten auftreten.By mounting the parallelogram support arm in a base part, which forms the only support surface on the floor of the means of transport, there is a significant improvement in vibration isolation. Some stretcher racks used to date are in fact resting at two or four points on the floor of the means of transport, so that vibrations can be initiated via all of these points. This can also result in interference vibrations if different loads occur at the individual support points.

Die Wahl einer einzigen Auflagefläche auf dem Boden des Verkehrsmittels wirkt sich so aus, daß Schwingungen, die an unterschiedlichen Punkten auftreten, ausgeglichen werden und Interferenzschwingungen prinzipiell nicht entstehen können.The choice of a single contact surface on the floor of the means of transport has the effect that vibrations which occur at different points are balanced and interference vibrations in principle not can arise.

Dadurch, daß das Basisteil in einer Laufschiene längsverfahrbar auf dem Boden des Verkehrsmittels angeordnet ist, wird das Basisteil während der gesamten Längsbewegung beim Herausschieben und Hineinschieben der Krankentrage in das Verkehrsmittel exakt geführt. Es ergibt sich außerdem eine bessere Verteilung der erheblichen Druck- und Biegekräfte zwischen dem Basisteil und dem Boden des Verkehrsmittels, so daß die Stabilität des Krankentragengestells auch ohne aufwendige Verstärkungen der Karosserie des Verkehrsmittels gewährleistet ist.Characterized in that the base part is arranged longitudinally displaceably on the floor of the means of transport, the base part is guided exactly during the entire longitudinal movement when the stretcher is pushed out and pushed into the means of transport. There is also a better distribution of the considerable pressure and bending forces between the base part and the floor of the means of transport, so that the stability of the stretcher frame is ensured even without expensive reinforcements of the body of the means of transport.

Die um eine senkrechte Achse drehbare Anbringung des Aufnahmetisches am Parallelogramm-Trägerarm ermöglicht es, den Aufnahmetisch außerhalb des Verkehrsmittels um 90̸° zu schwenken, also in eine Lage quer zur Fahrtrichtung auszurichten. In dieser Lage erhalten beide Begleitpersonen optimale Bewegungsfreiheit, so daß sie beim Aufsetzen und Abheben der Krankentrage besser die waagerechte Lage und die gleichmäßige Bewegung kontrollieren können.The mounting of the recording table on the parallelogram support arm, which can be rotated about a vertical axis, makes it possible to pivot the recording table outside of the means of transport by 90 °, that is to say align it in a position transverse to the direction of travel. In this position, both escorts get optimal freedom of movement so that they can better control the horizontal position and the even movement when putting the stretcher on and off.

Das zwischen dem Basisteil und dem Parallelogramm-Trägerarm angreifende hydraulische und/oder pneumatische Antriebs-, Feder- und Dämpfungselement übernimmt mehrere Funktionen. Im Zusammenhang mit dem Be- und Entladen führt es die Hubbewegung des Aufnahmetisches durch, wobei sich die dämpfende Eigenschaft darin auswirkt, daß der Beginn und das Ende der Hubbewegung weich einsetzt bzw. aufhört. Während des Transports werden die durch Vertikalbeschleunigungen der Karosserie des Verkehrsmittels hervorgerufenen Schwingungen ausgeglichen und gedämpft, damit es bei bestimmten Schwingfrequenzen nicht zu einem Aufschaukeln der Hubbewegungen kommt. Durch die Kombination als Antriebs-, Feder- und Dämpfungselement ergibt sich eine Mehrfachausnutzung derselben Bauteile, die den Material- und Gewichtsaufwand vermindert.The hydraulic and / or pneumatic acting between the base part and the parallelogram support arm The drive, spring and damping element takes on several functions. In connection with the loading and unloading, it carries out the lifting movement of the receiving table, the damping property having the effect that the beginning and the end of the lifting movement begin or end smoothly. During transport, the vibrations caused by vertical accelerations of the body of the means of transport are compensated and damped so that the lifting movements do not rock at certain oscillation frequencies. The combination as a drive, spring and damping element results in multiple use of the same components, which reduces the material and weight requirements.

Zweckmäßig liegt das Basisteil in Fahrtrichtung vor dem Aufnahmetisch.The base part is expediently in front of the shooting table in the direction of travel.

Hierdurch ergibt sich ein Befestigungsort für das Krankentragengestell, der etwa zentral im Fahrzeug angeordnet ist und sich durch die geringsten Hubschwingungsamplituden der Karosserie des Fahrzeugs auszeichnet.This results in a fastening point for the stretcher frame, which is arranged approximately centrally in the vehicle and is characterized by the lowest lift vibration amplitudes of the body of the vehicle.

Bei einer praktischen Ausgestaltung liegt die senkrechte Achse im Zentrum des Aufnahmetisches.In a practical embodiment, the vertical axis lies in the center of the recording table.

Bei dem sich so ergebenden Drehradius ist der nötige Verfahrweg, der für eine freie Drehbarkeit des Aufnahmetisches außerhalb des Verkehrsmittels zurückgelegt werden muß, am geringsten. Außerdem wird das Drehlager so im Schwerpunkt des Aufnahmetisches angeordnet, wodurch auch die Lagerbelastung minimal wird.With the resulting turning radius, the necessary travel distance, which must be covered outside the means of transport for the rotating table to rotate freely, is the smallest. In addition, the pivot bearing is arranged in the center of gravity of the receiving table, which also minimizes the bearing load.

Außerdem ist vorgesehen, daß der Parallelogramm-Trägerarm im Basisteil oder das Basisteil selbst um eine senkrechte Achse schwenkbar ist.It is also provided that the parallelogram support arm in the base part or the base part itself can be pivoted about a vertical axis.

Der Aufnahmetisch mit der Krankentrage und dem Patienten kann so auch innerhalb des Verkehrsmittels seitlich verschwenkt werden, um z.B. dem Begleitpersonal für Rettungsmaßnahmen den ausreichenden Bewegungsraum zu bieten.The table with the stretcher and the patient can also be swiveled sideways within the means of transport to e.g. to offer the accompanying personnel sufficient room to move for rescue measures.

Eine praktische Ausgestaltung des Parallelogramm-Trägerarms umfaßt vier parallele Trägerstäbe, die jeweils an einem dem Basisteil benachbarten Endstück und an einem dem Aufnahmetisch benachbarten Endstück angelenkt sind.A practical embodiment of the parallelogram support arm comprises four parallel support rods, each of which is articulated on an end piece adjacent to the base part and on an end piece adjacent to the receiving table.

Bei geringem Eigengewicht des Parallelogramm-Trägerarms ergibt sich so ein Höchstmaß an Steifigkeit gegen Wiegeschwingungen. Derartige Schwingungen in diesem Bereich sind nämlich höchst unerwünscht, da sie nicht kontrolliert gedämpft werden können.With a low weight of the parallelogram support arm, this results in a maximum of rigidity against Weighing vibrations. Such vibrations in this area are highly undesirable because they cannot be damped in a controlled manner.

Vorzugsweise bilden die Achsen der Trägerstäbe die Ecken eines in einer Querschnittsebene durch den Parallelogramm-Trägerarm liegenden Rechtecks.The axes of the support rods preferably form the corners of a rectangle lying in a cross-sectional plane through the parallelogram support arm.

Durch diese Ausgestaltung wird auch eine Steifigkeit gegen Torsionsschwingungen erzielt, die zu einer seitlichen Nickbewegung der Krankentrage führen könnten.This configuration also achieves a rigidity against torsional vibrations, which could lead to a lateral pitching movement of the stretcher.

Handelt es sich bei dem Verkehrsmittel um ein Landfahrzeug, so liegt das Basisteil vorzugsweise in der Transportstellung des Aufnahmetisches zwischen der Vorder- und der Hinterachse. Diese Auswahl der Anordnung des Basisteils berücksichtigt die aus Meßergebnissen gewonnene Erkenntnis, daß direkt über der Hinterachse die stärksten Vertikalbeschleunigungen auftreten. Im Gegensatz zu bekannten Krankentransportgestellen, bei denen die Auflagepunkte genau über der Hinterachse liegen, wird hier durch geeignete Auswahl des Befestigungsortes bereits die Höhe der Vertikalbeschleunigungswerte verringert, was sich günstig auf den Transportkomfort für den Patienten auswirkt.If the means of transport is a land vehicle, the base part is preferably in the transport position of the receiving table between the front and rear axles. This selection of the arrangement of the base part takes into account the knowledge gained from measurement results that the strongest vertical accelerations occur directly above the rear axle. In contrast to known patient transport racks, in which the support points lie exactly above the rear axle, the height of the vertical acceleration values is already reduced here by suitable selection of the attachment location, which has a favorable effect on the transport comfort for the patient.

Weiterbildungen und vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Ansprüchen, der weiteren Beschreibung und der Zeichnung, die ein Ausführungsbeispiel der Erfindung veranschaulicht.Further developments and advantageous refinements of the invention result from the claims, the further description and the drawing which illustrates an exemplary embodiment of the invention.

Fig. 1 zeigt einen Längsschnitt durch den Transportraum eines Krankenwagens 12 mit einem darin angeordneten Krankentragengestell 42. Das Krankentragengestell 42 umfaßt im einzelnen einen Aufnahmetisch 14, einen Parallelogramm-Trägerarm 16 und ein Basiselement 20̸, das mit dem Boden 18 des Krankenwagens 12 verbunden ist.1 shows a longitudinal section through the transport space of an ambulance 12 with a stretcher frame 42 arranged therein. The stretcher frame 42 includes in particular a receiving table 14, a parallelogram support arm 16 and a base element 20̸, which is connected to the floor 18 of the ambulance 12.

Das Basisteil 20̸ ist in einer Laufschiene 22 längsverfahrbar und kann von der dargestellten Position nach links verschoben werden, also aus dem Innenraum des Krankenwagens durch eine hinten angeordnete Tür herausgezogen werden. Das Basisteil befindet sich also in Fahrtrichtung vor dem Aufnahmetisch und liegt in der gezeichneten Position zwischen der Hinterachse und der Vorderachse.The base part 20̸ is longitudinally movable in a running rail 22 and can be shifted from the position shown to the left, that is to say can be pulled out of the interior of the ambulance through a door arranged at the rear. The base part is located in the direction of travel in front of the shooting table and is in the position shown between the rear axle and the front axle.

Eine senkrechte Achse 24 ermöglicht eine Drehung des Aufnahmetisches 14 am Parallelogramm-Trägerarm 16 und eine weitere senkrechte Achse 26 gestattet eine Schwenkbewegung des Parallelogramm-Trägerarms 16 im Basisteil 20̸.A vertical axis 24 enables the receiving table 14 to be rotated on the parallelogram support arm 16 and a further vertical axis 26 permits a pivoting movement of the parallelogram support arm 16 in the base part 20̸.

Der Parallelogramm-Trägerarm 16 besteht aus vier parallelen Trägerstäben 28, 30̸, 32 und 34, wobei die Trägerstäbe 30̸ und 34 jeweils durch die Trägerstäbe 28 und 32 verdeckt sind. Die Trägerstäbe sind in Endstücken 36 und 38 angelenkt, wobei das Endstück 36 dem Basisteil 20̸ und das Endstück 38 dem Aufnahmetisch 14 benachbart ist. In einer Querschnittsebene durch den Parallelogramm-Trägerarm 16 würden die Achsen der Trägerstäbe 28, 30̸, 32 und 34 die Ecken eines Rechtecks bilden.The parallelogram support arm 16 consists of four parallel support bars 28, 30̸, 32 and 34, the support bars 30̸ and 34 being covered by the support bars 28 and 32, respectively. The support rods are articulated in end pieces 36 and 38, the end piece 36 being adjacent to the base part 20̸ and the end piece 38 being adjacent to the receiving table 14. In a cross-sectional plane through the parallelogram support arm 16 would the axes of the support rods 28, 30̸, 32 and 34 form the corners of a rectangle.

Zwischen den Trägerstäben 32 und 34 des Parallelogramm-Trägerarms 16 und dem Basisteil 20̸ greift ein hydraulisches Antriebs-, Feder- und Dämpfungselement 40̸ an. Dieses besteht aus einem Druckzylinder und einem Druckkolben, wobei der Druckzylinder mit einem Druckaggregat 44 verbunden ist.Between the support rods 32 and 34 of the parallelogram support arm 16 and the base part 20̸, a hydraulic drive, spring and damping element 40̸ engages. This consists of a pressure cylinder and a pressure piston, the pressure cylinder being connected to a pressure unit 44.

Durch Verschieben des Druckkolbens innerhalb des Druckzylinders werden die Trägerstäbe 32 und 34 um ihre unteren Anlenkpunkte am Endstück 36 geschwenkt, wodurch der Aufnahmetisch 14 eine Hubbewegung vollführt. Die senkrechte Ausrichtung der Achse 24 sowie die waagerechte Ausrichtung des Aufnahmetisches 14 bleiben jedoch in jeder einnehmbaren Neigung der Trägerstäbe 28, 30̸, 32 und 34 erhalten.By moving the pressure piston within the pressure cylinder, the support rods 32 and 34 are pivoted about their lower articulation points on the end piece 36, as a result of which the receiving table 14 carries out a lifting movement. However, the vertical alignment of the axis 24 and the horizontal alignment of the receiving table 14 are maintained in every ingestible inclination of the support rods 28, 30̸, 32 and 34.

Das im Druckzylinder befindliche Arbeitsmedium kann kompressibel sein oder es kann im Kolben ein spezielles Federelement vorhanden sein, damit Vertikalbeschleunigungen durch gegensinnige Hubbewegungen des Aufnahmetisches 14 ausgeglichen werden können. Durch Ausgleichkanäle kann dafür gesorgt werden, daß diese Ausgleichsschwingungen schnell abklingen, also eine Dämpfung des Schwingungssystems erzielt wird.The working medium located in the pressure cylinder can be compressible or a special spring element can be present in the piston so that vertical accelerations can be compensated for by counter-stroke movements of the receiving table 14. Through compensation channels can be ensured that these compensatory vibrations decay quickly, i.e. damping of the vibration system is achieved.

Fig. 2 zeigt eine Ansicht eines Krankenwagens 12 von hinten bei geöffneter Hecktür. Man erkennt die auf dem Boden 18 angeordnete Laufschiene mit dem Basisteil, darauf den Parallelogramm-Trägerarm 16 sowie den Aufnahmetisch 14. Auf dem Aufnahmetisch befindet sich eine Krankentrage 10̸.Fig. 2 shows a view of an ambulance 12 from behind with the tailgate open. One recognizes the running rail arranged on the floor 18 with the base part, on it the parallelogram support arm 16 and the receiving table 14. On the receiving table there is a stretcher 10̸.

In der dargestellten Stellung ist der Aufnahmetisch seitlich verschwenkt, so daß auf der anderen Seite Platz für eine Begleitperson vorhanden ist.In the position shown, the recording table is pivoted sideways so that there is space for an accompanying person on the other side.

Der Aufnahmetisch 14 befindet sich hier in einer Hubstellung, bei der die Versorgung des Patienten vom Begleitpersonal im Stehen oder Sitzen durchgeführt werden kann.The receiving table 14 is here in a lifting position in which the attendant can care for the patient while standing or sitting.

Bei der Darstellung in Fig. 3 ist der Aufnahmetisch 14 aus dem Krankenwagen 12 herausgezogen und um 90̸° quer zur Fahrtrichtung geschwenkt. Er befindet sich außerdem in einer abgesenkten Stellung, in der die Krankentrage 10̸ leicht auf den Aufnahmetisch 12 aufgesetzt oder von diesem entfernt werden kann. An den beiden Längsseiten des Aufnahmetlsches 14 wird die Bewegungsfreiheit nicht durch andere Gegenstände beeinträchtigt, so daß das Begleitpersonal die Bewegungsvorgänge beim Aufsetzen und Abnehmen der Krankentrage besser kontrollieren kann.In the illustration in Fig. 3, the receiving table 14 is pulled out of the ambulance 12 and pivoted 90 ° transversely to the direction of travel. He is also in a lowered position in which the stretcher 10̸ can easily be placed on the receiving table 12 or removed from it. The freedom of movement is not on the two long sides of the receiving table 14 affected by other objects, so that the accompanying personnel can better control the movement processes when putting on and taking off the stretcher.

Zweckmäßig wird beim Einladen eines Patienten zum Krankentransport folgendermaßen vorgegangen: Ausgangsstellung ist zunächst die Stellung des Aufnahmetisches 14 gemäß Fig. 3. Der Patient wird dann auf die Krankentrage gelegt und die Krankentrage mit dem Patienten auf den Aufnahmetisch gehoben, indem das Begleitpersonal an den Stirnseiten der Krankentrage angreift.Appropriately, when inviting a patient to the patient transport, the procedure is as follows: The starting position is first the position of the receiving table 14 according to FIG Stretcher attacks.

Der Aufnahmetisch 14 wird nun durch Betätigen des Antriebs-, Feder- und Dämpfungselementes 40̸ angehoben und um 90̸° in Längsrichtung gedreht. Danach wird er in den Krankenwagen hineingeschoben und arretiert. Anschließend kann der Aufnahmetisch 14 noch in die für die Versorgung des Patienten geeignete Höhe angehoben und seitlich verschwenkt werden, wodurch sich die in Fig. 2 dargestellte Lage ergibt.The receiving table 14 is now raised by actuating the drive, spring and damping element 40̸ and rotated by 90̸ ° in the longitudinal direction. Then he is pushed into the ambulance and locked. Subsequently, the receiving table 14 can still be raised to the height suitable for the care of the patient and pivoted sideways, which results in the position shown in FIG. 2.

Beim Entladen wird in umgekehrter Reihenfolge vorgegangen.The unloading process is carried out in the reverse order.
